NPC Mod 1.1

Create NPCs, move them if you want, turn them, and remove them!

Moreover, there are 2 examples of how to make lua NPCs:
NPC that moves around the map
NPC that follows a random way

Console commands:
npc <X> <Y> - Creates a NPC at the given coordinate
npc_turn <ID> <DEG> - Rotates the chosen NPC (id) to a given direction (deg)
npc_move_left <ID> <LEN> - Moves the NPC (id) for the given length (len) to the left
npc_move_right <ID> <LEN> - Moves the NPC (id) for the given length (len) to the right
npc_move_up <ID> <LEN> - Moves the NPC (id) for the given length (len) up
npc_move_down <ID> <LEN> - Moves the NPC (id) for the given length (len) down
npc_remove <ID> - Removes the given NPC (id)

Lua functions:
npc_create(x,y) - Creates a NPC in the given X and Y
npc_turn(id,deg) - Rotates the chosen NPC (id) to a given direction (deg)
npc_move_left(id,len) - Moves the NPC (id) for the given length (len) to the left
